We observe a complex feedback loop rather than a simple inclusion of travel guides in fictional inspiration. Fiction creates an initial desire, but guides introduce a validation and feasibility loop that can itself generate a new form of inspiration. These planning tools refine or redirect the initial impulse, like when a film shows Venice but a guide reveals the little-known islands of the lagoon, creating a different desire. Their role is active in the decision system, as they can turn a vague desire into a concrete project, adding depth to the inspiration. It is not a simple subordination, but distinct influence mechanisms that are sometimes sequential and reinforce each other.
